<h1 class="topictitle1">Live Mounting VMware VMs</h1>
<div><p>This section describes how to live mount a copy of a VM to the original location or a new location to quickly start a new VM.</p>
<div class="section"><h4 class="sectiontitle">Context</h4><ul><li>Live mount can be performed using backup copies or replication copies. Data can be mounted to the original location or a new location. Note that replication copies cannot be used to mount data to the original location.</li><li>When data is mounted to the original location, if the original location is a cluster and vSphere DRS is not enabled for the cluster, the system mounts the VM to the host to which the VM belongs when the copy is generated.<p>When data is mounted to a new location, if the new location is a cluster, vSphere DRS must be enabled for the cluster. Otherwise, the live mount cannot be performed. You are advised to select a host in the cluster for mounting or enable vSphere DRS on the vCenter before mounting.</p>
<p>For details about how to check or enable vSphere DRS, visit the <a href="https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.resmgmt.doc/GUID-827DBD6D-08B7-4411-9214-9E126671457F.html" target="_blank" rel="noopener noreferrer">VMware official website</a>.</p>
</li></ul>
</div>
<div class="section"><h4 class="sectiontitle">Prerequisites</h4><ul><li>The maximum number of NFS volumes that can be mounted to an ESXi host by default varies with versions. Specifically, the maximum number is 8 for ESXi 6.7 and earlier versions, but 32 for ESXi 7.0 and later versions. If the number of live mount jobs created on a single target host exceeds the maximum number of NFS volumes that can be mounted, the mount jobs will fail.<p>In this scenario, you can change the number of NFS volumes that can be mounted to the ESXi host by referring to <a href="en-us_topic_0000001839187005.html">How Do I Change the Number of NFS Volumes Mounted to an ESXi Host?</a>.</p>
</li><li>If data is to be restored to a cluster, ensure that all hosts in the cluster can communicate with the logical ports of the backup storage.</li><li>If data is to be restored to a host, ensure that the selected host can communicate with the logical ports of the backup storage.</li></ul>
